Ionic Zip Library v1.9.1.6 GetEnumerator Method

Generic IEnumerator support, for use of a ZipFile in an enumeration.

Declaration Syntax

Visual Basic

Visual C++

public IEnumerator<ZipEntry> GetEnumerator()

Public Function GetEnumerator As IEnumerator(Of ZipEntry)

public:
virtual IEnumerator<ZipEntry^>^ GetEnumerator() sealed

Return Value

A generic enumerator suitable for use within a foreach loop.

Remarks

You probably do not want to call GetEnumerator explicitly. Instead it is implicitly called when you use a foreach loop in C#, or a For Each loop in VB.NET.

Examples

This example reads a zipfile of a given name, then enumerates the entries in that zip file, and displays the information about each entry on the Console.

CopyC#

using (ZipFile zip = ZipFile.Read(zipfile))
{
  bool header = true;
  foreach (ZipEntry e in zip)
  {
    if (header)
    {
       System.Console.WriteLine("Zipfile: {0}", zip.Name);
       System.Console.WriteLine("Version Needed: 0x{0:X2}", e.VersionNeeded);
       System.Console.WriteLine("BitField: 0x{0:X2}", e.BitField);
       System.Console.WriteLine("Compression Method: 0x{0:X2}", e.CompressionMethod);
       System.Console.WriteLine("\n{1,-22} {2,-6} {3,4}   {4,-8}  {0}",
                    "Filename", "Modified", "Size", "Ratio", "Packed");
       System.Console.WriteLine(new System.String('-', 72));
       header = false;
    }

    System.Console.WriteLine("{1,-22} {2,-6} {3,4:F0}%   {4,-8}  {0}",
                e.FileName,
                e.LastModified.ToString("yyyy-MM-dd HH:mm:ss"),
                e.UncompressedSize,
                e.CompressionRatio,
                e.CompressedSize);

    e.Extract();
  }
}

CopyVB.NET

Dim ZipFileToExtract As String = "c:\foo.zip"
Using zip As ZipFile = ZipFile.Read(ZipFileToExtract)
    Dim header As Boolean = True
    Dim e As ZipEntry
    For Each e In zip
        If header Then
            Console.WriteLine("Zipfile: {0}", zip.Name)
            Console.WriteLine("Version Needed: 0x{0:X2}", e.VersionNeeded)
            Console.WriteLine("BitField: 0x{0:X2}", e.BitField)
            Console.WriteLine("Compression Method: 0x{0:X2}", e.CompressionMethod)
            Console.WriteLine(ChrW(10) & "{1,-22} {2,-6} {3,4}   {4,-8}  {0}", _
              "Filename", "Modified", "Size", "Ratio", "Packed" )
            Console.WriteLine(New String("-"c, 72))
            header = False
        End If
        Console.WriteLine("{1,-22} {2,-6} {3,4:F0}%   {4,-8}  {0}", _
          e.FileName, _
          e.LastModified.ToString("yyyy-MM-dd HH:mm:ss"), _
          e.UncompressedSize, _
          e.CompressionRatio, _
          e.CompressedSize )
        e.Extract
    Next
End Using
